Apparatus, method and medium converting motion signals

Abstract

An apparatus, method and medium converting a motion signal, which is capable of controlling the motion of the pointer according to a user's intention by removing noise using a filter for the detected motion signal of the pointer in accordance with the moving speed of the pointer. The apparatus includes, a motion detecting unit to detect a motion, a determining unit to determine a type of motion signal according to the detected motion, and a filter unit including at least one filter to convert the motion signal using a filter that corresponds to the type of motion signal, the filter being selected from among the at least one filter.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority from Korean Patent Application No. 10-2006-0136780 filed on Dec. 28, 2006 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference in its entirety.BACKGROUND[0002]1. Field[0003]One or more embodiments of the present invention relate to an apparatus, method and medium converting a motion signal, and in particular, to an apparatus, method and medium converting a motion signal that uses different filters to a motion signal for a sensed pointer on the basis of a movement speed to remove a noise.[0004]2. Description of the Related Art[0005]A direct pointing device is an input device that extracts a display area of a display device such as a digital TV, and detects a current position of a pointer on a screen to control a position of the pointer that is displayed on the screen of the display device.[0006]The direct pointing device adopts a direct mapping method, that...

AI Technical Summary

Benefits of technology

The solution effectively filters out unwanted motion signals caused by hand tremors and unintended movements, allowing the pointer to move in accordance with the user's intention, improving accuracy and control over the pointer's position.

Problems solved by technology

However, when displaying a pointer in a display area by using such a direct pointing device, it becomes difficult for a user to determine a position of the pointer as a distance between the display device 400 and the direct pointing device becomes larger.

Further, if the user does not use a direct pointing device, but a general pointing device, it is difficult for the user to determine the position of the pointer due to hand tremors, which become more serious as the distance between a panel on which the point is displayed and the pointing device becomes larger.
